-Subject: [PATCH] spidev: Completely disable the DT warning
-
-The upstream SPI and DT maintainers are completely opposed to declaring
-in Device Tree that an SPI CS line is to be managed by the spidev
-driver, even though the facility is useful on a hobbyist device like a
-Raspberry Pi where arbitrary devices can be attached, and the
-alternative to DT declaration (spi_board_info) has been almost entirely
-rendered obsolete by DT.
-
-Continue to override their objections by disabling the warning.
